The construction site environment of the power transmission line iron tower erection is complex and the conditions are variable, and particularly under the condition of a large number of mountainous terrain, the suspension holding pole is often adopted for decomposing and assembling the tower. When the suspension holding pole is used for lifting a hanging part, the holding pole is suspended inside the iron tower, and the holding pole is too close to or collides with the assembled tower body, so that safety accidents such as the holding pole is broken, the hanging part falls off and the like can be caused. Therefore, the distance from the suspension holding pole to the assembled tower body is monitored, and the method has important significance for guaranteeing the safety of the tower construction of the overhead transmission line.

At present, the method for acquiring the distance from the suspended holding pole to the assembled tower body is mainly to observe the distance through ground artificial naked eyes and judge whether the holding pole is in a safe state or not by virtue of construction experience.
